We are Praktikal

We believe that hands-on learning is what every student needs, and that the eye is always the best judge.

Our mission is to create a great teaching experience for teachers through a coherent and practical ecosystem, so that they feel confident, inspired and successful. To create the most engaging physics lesson for students and thereby increase their interest in learning science.

Our next steps

To date, over 100 schools have joined Praktikal’s ecosystem, and our next target is to reach 250 schools.

Prepare all primary school physics courses and the necessary test kits.

To prepare a set of equipment for home use.

What do learning physics and cycling have in common?

At first glance, it may seem that there is little that can be done to prepare for cycling. Learning is a matter of trial and error. If you turn the handlebars the wrong way, or don’t lean or lean too much, the mistakes you make will give you immediate feedback. However, once you get the hang of it, you’ll never forget it.

Physics, on the other hand, is about the deepest secrets of nature, many of which have only been discovered by the brightest minds in human history. But theory often plays a major role in learning them. It is not difficult to learn the laws of nature dryly by rote, but it is about as tedious and useless as trying to memorise a cycling manual. Better to get in the saddle and ride!

On the other hand, some of us have carried out an experiment in school where we measure the friction force by attaching a clog to the end of a spring. Were you surprised by such an experiment? Did it provide you with a different or memorable experience? Did it give you a better understanding of nature or technology? Probably not.

But maybe it’s also possible to put together experiments or whole lessons in physics, where learning is like the experience of cycling? Where students can make mistakes that provide quick and clear feedback on the phenomenon being learned? Which would also be affordable, manageable and accessible for the teacher? Also for all those who are not the next Newton or Tesla.

We believe that this is possible.

Praktikal was designed to make learning science exciting, emotional and memorable. It has grown into an ecosystem of science teaching, where learning content, methodology and tools form a synergy.

How was Praktikal born?

For years, Omari Loid and Kaido Reivelt have been passionate about popularising science. Their paths crossed for the first time in 2006, when they started working together on the Three Little Pigs science curriculum, which Omari had been running by himself up until then.

When Omari invited Kaido to develop the piglet crates in the spring of 2021, Kaido set out to do something much bigger and better. By then, he had already created a number of physics teaching prototypes, which he himself had used in schools and which were of great interest to other physics teachers.

This is how Praktikal was born in May 2021.

Over the next few months, Eva Pedjak and Oleg Shvaikovsky joined as co-founders.

As a successful entrepreneur and physics enthusiast, Eva wanted to improve physics education. Oleg had recently left the board of Nortal, and dedicated himself to education; both as an investor, and as the founder of St. John’s School, and a physics teacher.

The founders believe that all teachers are capable of delivering an engaging and exciting lesson – especially if given the right tools.
